Abstract
AbstractThe exploitation of high energy density lithium−oxygen batteries (LOBs) holds significant importance for energy storage and applications. An efficient cathode catalyst can effectively prevent the accumulation of the insulating insoluble discharge product Li2O2, thereby enhancing the electrochemical performance. Spinel materials, widely available and cost‐effective, exhibit superior catalytic activity, making them ideal candidates for LOBs cathode catalysts. This review aims to offer a comprehensive and insightful overview of the recent progress in the design of spinel‐type electrocatalysts for LOBs. This review exhaustively summarizes various modification strategies applied to spinel materials and emphasizes the influential role of catalytic descriptors in designing highly active spinel‐type catalysts. This review provides guidance for the design and utilization of high‐performance spinel‐type catalysts, thereby contributing to the dynamic development of LOBs.
